T all whom it may concern:

Be. it known that I, LEO SIMMONS, acitizen of the United States ofAmerica, and a resident of Washington, District of Columbia, haveinvented certain new and use ful Improvements in and Relating to Flush-v ing Apparatus, of which the following is a specification.

This invention relates to improvements in flushing apparatus; and thenature and objects of the invention will be readily understood bythoseskilled in the 'art in the light of the following explanations of theaccompanying drawings that illustrate what I now believe to be thepreferred mechanical expressions or embodiments of my invention fromamong other forms, constructions and arrangements within the spirit andscope thereof.

An object of the invention is to provide improvements in combinations,constructions, and arrangements with the end in View of producing anexceedingly desirable and improved apparatus or so-called valve. .VViththis and other objects in view my invention consists in certain novelfeatures, combinations and constructions as more fully and particularlyexplained and specified hereinafter.

Fig. 13 is a section on the line 1313, Fig. 3, on an enlarged-scale; I

In the particular example illustrated for purposes of explanation, anelongated usually vertical casing is provided consistingiof severallongitudinal alined hollow or tubular sections usually detachably unitedorcoupled together through the medium of water-tight screw threadedcouplings or connections. For instance, the casing can be composed of atop end tubular section 1, an intermediate section 2, and a lower endsection 3,although I do not wish to so limit all features of myinvention.

In this particular example, the top section 1 provides a chamber for thepressure or service water and a flushing water outlet or port throughwhich the flushing water enters the section 2. The section 2 providesaflushing water chamber or passage having a flushing water outlet forconnection to the toilet to be flushed. The section- '3 carries the dashpot and provides a water well open I to the flushing water passageofsection 2, The tubular section 1 is normally closed at the upper endwater tight removable top closure, and at its lower end provides aflushing water outlet duct or port 1, longitudinally alinedwith thecasing sections and discharging into the upper end of section 2. Thelower end of section 1 pro 'vides an annular upwardly facing ledgesurroundlng said outlet l and forming a seat or supportifor the usuallyflexible annular heavy packing washer 4. The flu shing water portordischarge through this washer is normally closed by main flushingvalve 5, and auxiliary or pressure relief valve 6, as more fully setforth hereinafter.

In this example,-the top section 1 is formed, between its upper andlower ends,

with a lateral or side service or pressure --water inlet 1*, formed forcoupling to any suitable service or other pressure water supply pipe orconnection 7 j The otherwise open upper'end of section, 1

1, is normally closed by a removable end pressure-water closure cap 8,having a depending internally threaded flange 8 that surrounds andscrews over the externallythreaded upper end of section 1. This closureis usually provided with an internal packing washer 9 to form a tightjoint. The closure cap 8, is formed with a fixed central verticalupstanding post or spindle 8 closed against passage of liquid from theinterior of the casing to the exterior of the closure, and the closureis formed with a vertical guide bore 8, longitudinally of said post andopen at its lower end into the cas ing. This guide bore loosely andslidably receives the upstanding longitudinal guide stem 6 rigid withrelief valve 6. The post 8 is exteriorly formed to provide the closurewith rigid nut or wrench receiving faces 8 the exterior portion of thepost above nut 8, being reduced and screw threaded, to provide ledge orshoulder 8 on the nut.

The'upper side of the approximately flat top of the closure, is alsopreferablyformed with an annular ledge or shoulder 8 adj a cent to thejunction of the depending flange 8 with said flat top. These shouldersor seats 8 8, are designed to receive the top and lower edge,respectively, of a removable cup-like perforated cover cap 10, confinedto the closure by any suitable means, such as cap nut 11, for instance.The approximately flat top wall of the cap 10 is formed to rest on theshoulder 8 and is perforated,

for the passage of threaded post 8 The lower edge of the dependingannular wall of cap 10, is formed to fit and be centered by the seat 8.The clamp nut 11, is formed to cover the projecting post 8 and removablyscrew thereon down onto thecover cap. The exposed surfaces of the nut11, cover cap 10, and end closure 8, are nickel plated or otherwisepolished and finished, to comply with present trade conditions withrespect to bath room and like plumbing fixtures.

Access to the flushing valves 5, .6, the washers, and certain otherinterior parts of the apparatus, is gained by unscrewing and removal ofthe pressure cap 8. The wrenches usually employed by plumbers andmechanics seriously damage and mar the exposed ornamental plated orfinished polished surfaces of plumbingfixtures to which such wrenchesmust be applied. I hence provide the readily removable ornamentalexteriorly finished perforated slip cover cap 10, that must first belifted from the casing, before the pressure cap 8, can be reached forremoval, and that normally covers and conceals those surfaces of thepressure cap that must be engaged by the wrench during the operation ofremoving the pressure cap. The surfaces of the pressure cap covered orconcealed by\the perforated cap, can hence be left unfinished and not incondition to be post 8 and the top of the pressure cap 8,

and as readily reapplied. When in normal position, the exposed surfacesof the pressure cap, cover cap and clamping nut 11, provide a compactapparentlyone piece finish at the upper end of the casing. Theperforations.

10 in the cover cap are intended to be clearly visible to the plumber ormechanic for the purpose of indicating the presence of a mere finishingcover that does not enclose a water space or chamber and that must beremoved to gain access to the pressure cap, ntending to warn the plumberor mechanic against applying a heavy rough tool such as a pipe wrench,to the cover cap.

In the specific example illustrated, the

washer 4, isclamped againstits supportingledge by metal ring 12, andthis ring is held down on the outer edge portion of the washer by spacedupstanding vertical arms 1%, rigid with the ring, and the spider-likeframe consisting of said ring. and arms, is held down by ring nut 13,screwing into the internally threaded upper end of easing section 1. Theframe consisting of the ring and arms is removable and slidablelongitudinally along the cylindrical inner surface of thesection 1, andis held. against rotation therein by longitudinal rib on the outersurface of the upper end of one of said arms slidable vertically inavertical longitudinal groove in theinner surface, of the upper end ofthe section 1.

On removal of the end closure the ring 'nut can be adjusted to tightenor loosen the washer, and on removal of the nut, the ring and its armscan be removed to permit removal of the washer. The arms do not obstructthe service water inlet and do not interfere with or obstruct theflushing valves or the cooperation of the washer 4 therewith. V

The lower end of section 1 longitudinally telescopes with the upper endof section 2 and said section ends are oined together for longitudinalremoval by longitudinal intermeshing screw threading, and the sameistrue of the meeting longitudinally telescoping lower end of section 2and upper end of section 3.

In the example shown, the flushing and relief valves are of the lifttype and seat by gravity and water pressure. The main valve 5, isusually of metal, conical in shape, and fits and depends within thewasher 41, and is formed with a central vertical pressure relief duct5*, leading from the water pressure chamber in section 1, to theflushing I water chamber or passage in section 2. This relief passage isnormally closed by the 00111- cal relief valve 6, usually integral withguide in said recess on said shoulderand the valve '6 normally seats onthe 'washer-and"extends down'into the centralopeningthereoiif The washer5? is removable. and is normally formed with a central Verticallongitudinalclamped to its supporting shoulder by removable ring 5,screwing down into the rece'ss in valve 5, and formed with an openworkupwardly extending spider like fraine 5 projecting. abovethe reliefvalve 16,-and spaced upwardly therefrom in position to be engagedflbythe upper end of the relief valvewhen that valve has completedits'upward movenient relativeto the valve 5 and instituted the pressurerelief flow of water through duct 5*, of valve. 5." Continued up wardmovement of valve 6, thenliftslthe valve 5, and the two valves? thenvcontinue their upward strokes together, and thevalve 5 remains looselysuspended from the upper end of valve 6, while valve 5',remains aboveits seat. The lifting or stop frame 5', is nor mally spaced from. valve6Tand' 'is always open to water flow,ltherethrough, and the main valve 5is hence loosely hung by-said frame and is free for lateral swing or"movement with respect tovalve 6 to permit relative lateral freedomai'idz-propericentering and seating on its Washer. The casing section2," intermediate its. ends, is formed with lateral or radial'fiushingWaterroutlet-Q, formed to 'receive iflushing water pipe or otherconnection 15, for attachment to the toilet or other device or apparatusto be flushed. I

The otherwise open lower endof section 2', is closed bythe section 8,the upperfend of which is removably unitedto the lower end-of section-Q'by a screw threaded connection.' -f r Y The well sectionl3 is hollow,closed'at'its lowere'nd, and open at its upper end to the flushing waterchamber or'pass'age' ofsection 2, and its annular vertical walland lowerend, are closed against passage of water therethrough. 1 v A verticallyelongatedi open-upper end dash pot cup 16, is carried by and arrangedlongitudinally of and within section 3 in normally fixed relationtheretof This J cup 8 is of reduced externalZcrossTsectional dimensionsthroughout its length'with respect to the internal dimensions ofsection'i'r3; to

provide a water well 17, withirisectionw surrounding thevert-i'eal-wallof cup 16 and between the'lower ends of the cupandrsection 3, with said water vwell open at its upper end to theflushing waterchamber of section 2.- This cup is mounted in an elevatF-ed position in the section. 3, in the particular example"illustrated,through the medium,

of a tubular nipple 16", forming a reduced central" longitudinal rigideXtens ionof' the cup'and" depending from the otherwise closed floor orend wall thereof. The longitudinal bore of thi'sjrigid extension nipple"ex'tends'completely through the nipple and at its upper end opens intothe cup through the floor thereof.

The' bottoni end w-all of section 3," is

ly screwed threaded bore th'erethrough. The cup-issecured to and insection 3, by inserting the cup longitudinally into'the sectioirthroughthe open'upper end ofthe seeition, and screwingtheni'pple 16, into saidbottom bore of thesection', preferably, until the flange or annularshoulder 16 of the nipple" tightly abuts the top f ac'efof 'the floor ofsection 'The lowerend of the cup'is held elevated above theffloorofsection 3 by the non-threaded base or upper length of nipple 16,between shoulder 16*, and the cup fioor or endylocated in the water well"17 of section 3.

This base 1 portion is exteriorly' and tan"- a narrow horizontally'o'r'trarisverselyelon- I gated slit-like outlet "or' relief; port "a,tangentially of the cylindrical nipple bore; Thisslit'con stit'utes aport communication from the lower end of the ccup interior through saidbore 'to 'thelower end of the water well17'. f I

This slit port a is closed and*opened and its area or capacity iscontrolled by, a rotary plug valve 18 in the form of a cylinder having atangential flat portion 18 extending through its upper'or inner end.This plug 18 extends longitudinally through the bore of the dash potcup'nipple and'cl'osesthe sarne against water flow therethrough andleakage to the exterior from the lower or outer end of the bore. Theplug extends to and'depends'at the exterior of the section 3' and isformed with exterior finger head 18* readily accessible to the fingers'for rotation of the plug toset the same at the required mentarylongitudinal A intermeshing screw threaded portions forming packingagainst water leakage, enabling the plug to be re-- moved, and renderingit possible to screw the plug-inwardly to a safe point to-prevent'leakage so that it may then berotated to:

adjust the passage and 'gauge'the length of time in which the valves 5and 6 are to remain open and thus regulate the required flush of water.The upper or inner cylindrical portion, excepting the flattened part 18,

of the plug fits the cylindrical inner surface of the nipple bore with arunning fit so that the slit port a, will be operatively closed by thecylindrical surface of the plug, when the plug is turned or rotated to aposition with the flat face 18, remote from the V-shaped slit port a.The flattened portion of the plug forms a longitudinal water. passage,within the nipple, that is open at its upper end into the dash pot cupand is otherwise closed against liquid escape or leakage, except whenthe flat portion 18*, is opposite slit port a, so that the portion ofthe nipple wall containing said slit forms a portion of the wall of saidlongitudinal water passage. When the plug is in this just mentionedposition, fluid flow to and from the cup is established through saidslit port and the nipple. By slightly rotating the plug, the slit porta, can be closed, or can be opened throughout its length, or can befractionally opened to the extent required by the desired quantity ofwater to be discharged at each flushing operation.

The stem that controls the main and relief valves 5, 6, is provided atits lower end with a piston 19 vertically movable in the dash pot cup16, and this piston and the cup are relatively formed and constructed tocause inflow of flushing water into the cup under the piston on theopening movements of the main and relief valves, i. e. on the upwardmovement of the piston so that the cup will be full'of water before thepiston starts on its downward movement. The upward movement of thepiston also exerts suction pull through the slit port a, to draw waterthrough said port and the nipple into the bottom of the cup. The pistonand cup are also relatively formed to reduce to the mini mum waterleakage or pressure relief from the cup during the downward movement ofthe piston, except through the slit port a.

It will be observed that the V or flaring form of the port a, providessharp or feather edges forming the longitudinal walls of the port,whereby the inrush and outrush of water during the ascent and descent ofthe piston, will readily free the port from sediment or other foreignmatter tending to clog or choke the same. These feather edges tend toprevent sediment and the like from collecting in and choking the port.

Various constructions can be provided for causing quick filling of thecup, although I show the piston provided with a flexible cup washer 19*,having .a depending annular flexible skirt formed to contract for waterpassage on the upward stroke of the piston and to expand against theinner surface of the cup and against upward passage of water on thedownward movement of the piston. Also, if so desired, the internaldiameter of the cup can be enlarged at the upper end of the cup to aidin such rapid filling of the cup with water under the piston. Also, someinflow of water to the cup through port a, from the water well, willtake place during the upward stroke of the piston, while the speed ofthe descent of the piston and parts then carried thereby will becontrolled by the outflow through and consequently by the area orcapacity of the port a, which can be most accurately and readily variedor adjusted by plug 18. The valve stem 14 forms a stiff valve liftingand controlling rod-like member from the piston to the valves, and inthe example shown is composed of two longitudinal alined sectionsremovably united by longitudinal screw thread joint 14 for purposes ofassembly and taking down, and if need be, to permit longitudinalshortening or extension of the lift stem.

Various means can be employed, operative from the exterior of thecasing, for lifting the stem with the dash pot piston and the relief andmain flushing valves to initiate the flushing flow, and for thenreleasing the stem so that the dash pot and piston can control thedescent of the valves and the length of time of the flushing water flow.

However, I show improved and peculiarly advantageous means for thispurpose. In the particular example illustrated, the casing section 2, iscast or otherwise formed at a point remote from outlet 2, with a hollowlateral bulge or offset 2", forming a lateral or side recess or chamberopening into the flushing water chamber of the section and otherwiseclosed against water outflow to the casing exterior. Avertically-swingable horizontally-disposed lifting member or lever 20,is fulcrumed in said bulge on transverse axis 21, and is arranged in thebulge and extends therefrom transversely across section 2, past thelifting stem 14 although I do not wish to so limit all features of myinvention.

.The shaft pivot pin or axis 21, extends transversely across the bulgeor offset 2, and is supported by the opposite vertical walls thereof,and, in the example shown, the outer end of the lever member 20, isformed with a transverse hub receiving and rotatable on the axis 21.

The lever member 20, is operatively connected with the lift stem 14 inany suitable manner or by any suitable means, to operate said stem tolift the flushing valves (main valve 5, and relief valve 6) to start theflushing operation. For instance, I show the free end of the levermember loosely crossing the lower section of stem 14, under a liftingshoulder 14", of the stem in such manner that when the lever member isrocked to elevate its free end, such end will strike said shoulder andthrough the medium thereof elevate the stem to lift the flushing valves.If so desired, the free end ofithe lever member can be longitudinallyforked or bifurcated and thus loosely straddles the lifting stem belowcorresponding lateral downwardly-facing lifting shoulders 14, formed on"opposite sides of the stem, and above upwardly-facing lateral shoulders14, correspondingly arranged on opposite sides of the stem. If sodesired, these shoulders 14, 14, can be of the approximate knife-edgetype, and the stem can be flattened or reduced in thickness at itsopposite sides between lifting shoulders 14 and depressing shoulders 14,although I do not wish to limit all features of my in vention to suchconnection between the lever member and the stem nor to the bifurcatedand twin shoulder arrangement.

Suitable means are provided to operate the lever member to lift theflushing valves (first the relief valve, and then the main valve throughthe 'medium of the relief valve) to start the flushing operation bylifting engagement of the member with shoulders 14, and to then releasesaid member, permitting its free end to drop to and rest on the stop ordepressing shoulders 14.

In the example illustrated I show a thrust cam as means of actuating thelever member on its valve-lifting stroke, and then to permit the valveto close under action of gravity and the flushing water flow orpressure, whilethe speed of valve closing movement is controlled by thedash pot device. Such lever member operating vmeans, in this ex ample ismounted in and carried by the casing bulge or ofiset 2, and embodiesavertical oscillatory spindle or shaft 22, extending from a point at theexterior of the casing to a point within the same, and extending throughthe top wall of the offset 2, and carried by 'androtatable in a suitablepreferably removableplug in said wall forming a journal or hearing boxfor said spindle. At its upper end, at the exterior of the casing, saidspindle is equipped with a lateral operating handle 23, normally fixedthereto. In the upper part of the chamber within the casing offset 2,the lower end of the spindle is formed with or carries a disk 24 fixedthereto and arranged centrally above the fulcrum of the lever member 20.The upper end or side of this disk provides an annular shoulder bearingagainst the top wall or closure of the casing offset to receive the up:ward thrust of the cam disk in action and limit upward movement of thespindle 22. The fulcrum hub of the lever member 20, is provided with afixed stud or pin 20, projecting upwardly and outwardly therefrom at anangle, and a grooved roller 20, is mounted to revolve on said pin. v

Thedisk 24 is formed with a depending rounded thrust cam and trip noseor toe arranged a distance radially from the longitudinal axis of thedisk 24 and its spindle and 'hence'e'ccentric with respect thereto anddesigned to engage and gradually depress the roller 20 and consequentlyswing the lever member on its valve lifting stroke, as the handle 23 isswung on an operative stroke, and to slip past said roller and free thelever member before said handle completes such stroke. This nose or toeis double to thus act on and slip past the roller, on each operativeswing of the handle, i. e. when the handle is swung forward and when thehandle is swung backward, referring to Fig. 9. This is provided for bylimiting the back and forth swing of the handle to an are prescribed bystops 26 (Fig. 13) projecting inwardly from the vertical wall of thecasing offset. 2, and cooperatingwith stop shoulders or a radial lug 24rigid'with the disk. In this instance, the stop 24 is arranged at theouter side of and is centrally arranged with respect to the dependingoppositely curved portions of the working or operative edge 24", of saiddepending toe or nose. The disk is formed with a depending edge trackarranged above the roller 20, and this track embodies the elevated endportions 24, approximately concentric with the axis of the disk thatgradually curve downwardly and converge to form the working edge 24 ofthe said nose or toe having acurved crown or tip toslip past the roller'in'either direction. The working edge 24,is formed to ride on thegrooved roller 20 and depress the same the maximum distance, say whenthe handle 23, reaches a position about mid way its stroke, see middleposition shown by dotted lines Fig. 9, and the flushing water willcontinue to flow as the flushing valves are held elevated so longas theoperator holds the handle in this middle position. However, if theoperator does not hold the handle in this position, the curved cam nosewill slip past the roller, thereby freeing the lever member after theflushing valves have been lifted their full .upward stroke permittingsaid member to drop by gravity onto the shoulders 14 leaving the memberand the valves then entirely free and independent of the handle 23 andthe thrust trip means. g

' The cam arrangement attains a powerful leverage action, by theapplication of but slight force to handle 23, to depress the short armof the lever the shortdistance necessary to the relatively long fulllift of the flushing valves through the long upward stroke of the longarm of the lever member, and vthe parts can be moved to cause aflushingoperation by'swinging the handle in, either direction fromeither stop 26 toward the other stop 26.

. The constructions disclosed'by my Patents No. 1,531,514. dated March31, 1925, and No. 1,534,537 7 dated April 21, 1925, are not hereinclaimed apart from the improvements disclosed by the instant case, but Ido not desire to limit said improvements to use in connection with saidconstructions.

It is evident that various changes, modifications, and variations mightbe resorted to without departing from the spirit and scope of myinvention and hence I do not wish to limit myself to the exactdisclosures hereof.
